The Murphy 0-3000 PSI Panel Mount Mechanical Pressure Swichgage with Stainless Steel Bourdon Tube and Socket OPLFC-S-3000 is a panel mounting version of the OPLC. This Swichgage model is a combination pressure indicating gage with an adjustable low and high limit switch. The limit switch can be wired directly to electric pilot circuits to operate alarms and/or shutdown engines and electric motors. The limit switch is accessible from the front of the gage and the contacts have a self-cleaning motion to enhance electrical continuity.

It has all of the features of the OPLC except the low limit contact lockout. The lockout must be done externally through the control circuit or with the optional “SA” lockout. The OPLFC is typically used in control panels such as for compressors, pumps, etc. This version can be environmentally sealed with either the “ES” or “OS” options. Contact lead termination is by pigtail wires. Pointer closure against either of the adjustable contacts completes the pilot-duty circuit.
